The document discusses the history of the study of force and motion. It describes Aristotle's view of natural and forced motion. It then talks about Galileo's experiments with balls rolling down inclined planes, which helped establish the concept of inertia. Finally, it introduces Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

1) The document discusses the magnetic force on a moving charge and current-carrying conductor in a uniform magnetic field. It defines magnetic force and derives the formulae for force on a charge and conductor.
2) Magnetic force on a moving charge is directly proportional to the charge, velocity perpendicular to the magnetic field, and magnetic field strength. The formula derived is F = qvBsinθ.
3) Magnetic force on a current-carrying conductor is directly proportional to the current, length of conductor perpendicular to the magnetic field, and magnetic field strength. The formula is F = ILBsinθ.
Classical mechanics vs quantum mechanicsZahid Mehmood
Classical mechanics can explain motion based on Newton's laws of forces and particles. However, experiments at the atomic scale produced results inconsistent with classical theory. Max Planck explained blackbody radiation by quantizing electromagnetic radiation. Later, experiments showed matter also exhibits wave-particle duality, requiring new theories like quantum mechanics.
